Measuring Resistance To Check For Open Circuits

WARNING: This page is about a different car, the 2002 Saab 9-5 and 2001 Saab 9-5. However, it is still accessible from the selected car via links, so may be relevant.
  1. Make sure there is no power being supplied to the component or lead to be checked (e.g. by removing the relevant fuse).
  2. Set the multimeter to ohm measurement and connect the instrument to each end of the component/lead to be checked.
  3. Jiggle the relevant wiring harness while observing the ohmmeter. The resistance for a wiring harness should normally be less than 1 ohm. Special values apply to components.
